685-685: Use "macOS" instead of "Mac OS" per Apple style guide.Replace "Mac OS" with "macOS" in all tab headers at lines 685, 801, 813, 830, and 841 to follow Apple's official naming convention.
🔎 Proposed fix for style consistency
- === "Linux/Mac OS" + === "Linux/macOS"Apply this change to all affected lines.
Also applies to: 801-801, 813-813, 830-830, 841-841
811-811: Fix grammatical issues: hyphenate compound adjectives and remove redundant phrasing.Line 811 has two style issues:
- "high time consumption is identified" → awkwardly worded; consider "high latency is identified"
- "time consuming service" → should be "time-consuming service" (hyphenated compound adjective)
🔎 Proposed improvements
- If a method with a high time consumption is identified, then take the 5 most time consuming service and database calls, with the same correlation ID of the method logs, and find out the unusually time consuming call. + If a method with high latency is identified, then take the 5 most time-consuming service and database calls with the same correlation ID and find the unusually time-consuming call.
828-828: Remove redundant phrasing at line 828."high time consumption cannot be identified" → "high latency cannot be identified" or simply "cannot identify high latency" is clearer.

Pull request overview
This PR adds Windows/PowerShell command equivalents to existing Linux/Mac commands in the correlation logs monitoring documentation, addressing the lack of Windows-specific instructions for log analysis tasks.
Key Changes:
- Added tabbed code blocks with separate "Linux/Mac OS" and "Windows" variants for log analysis commands
- Updated placeholder usage from literal
correlationIDto<correlation_ID>for consistency - Provided Windows equivalents using
type,findstr, andsortcommands
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
| type correlation.log | findstr "<correlation_ID>" | findstr "|HTTP" | sort | ||
| type correlation.log | findstr "<correlation_ID>" | findstr "|jdbc|" | sort | ||
| type correlation.log | findstr "<correlation_ID>" | findstr "|ldap|" | sort |

The Windows commands are missing the cut equivalent to extract the 4th field (time values) from the pipe-delimited log entries. The Linux version uses cut -d "|" -f4 to extract only the time values before sorting, but the Windows version skips this step and tries to sort the entire log lines. This will not produce comparable or useful output. Consider using PowerShell's ability to split strings and select specific fields, or provide an alternative approach that extracts the time values.

This command has multiple issues: 1) The for /f syntax shown here is for batch files (cmd.exe), not PowerShell. In batch files, loop variables use %a, but in PowerShell you would use $a. 2) The command attempts to pipe to more and then process with for, which won't work as written. 3) Like other Windows commands, it's missing numeric sorting capability. 4) The entire syntax is not valid PowerShell and won't execute correctly when copy-pasted. This needs to be rewritten as proper PowerShell syntax.

The indentation level of the "Then the entry..." text is inconsistent with the tabbed code blocks structure. This text should either be outside the tabs (applying to both OS variants) or inside both the Linux/Mac OS and Windows tabs. Currently, it appears to be inside only the Windows tab section, which could confuse readers about whether this instruction applies to both platforms.

The Windows sort command does not support the -n numeric sort flag that the Linux version uses. This means the Windows version will perform alphabetical sorting instead of numeric sorting, which will produce incorrect results. For example, "100" will sort before "20" alphabetically. To achieve numeric sorting in PowerShell, you should pipe the output to PowerShell's Sort-Object with the -Property parameter cast as an integer, or parse and sort the values appropriately.

811-811: Minor: Use hyphens for compound adjectives and reduce redundancy.The phrase "time consuming" should be "time-consuming" (lines 811: appears twice). Additionally, "high time consumption" is somewhat redundant and could be tightened to "high consumption" or "high latency" for clarity.
🔎 Suggested improvement
-This will give the time consumed by each method in ascending order. If a method with a high time consumption is identified, then take the 5 most time consuming service and database calls, with the same correlation ID of the method logs, and find out the unusually time consuming call. +This will give the time consumed by each method in ascending order.

685-693: ✓ OS-specific command blocks properly introduced for isolation step.The initial tab structure effectively provides both Linux and Windows variants for filtering logs by correlation ID. Commands are clear and readable.
801-809: ✓ Windows command now correctly extracts and sorts the duration field.The updated PowerShell command uses
ForEach-Object { ($_ -split '\|')[3] }to extract the 4th field (index 3) andSort-Object {[double]$_}for numeric sorting, matching the Linux behavior. This resolves the previous concern about missing field extraction.
820-825: ✓ Windows commands for correlation-ID filtering properly extract duration field.All three Windows variants (HTTP, JDBC, LDAP) now correctly extract field index [3] and apply numeric sorting with
{[double]$_}, ensuring results match the Linux equivalents.
835-849: ✓ Highest duration detection now works correctly on both platforms.The Windows commands for finding the highest time value now use the same field extraction and numeric sorting pattern, ensuring consistent behavior across OS variants.

830-839: Fix indentation of transitional note at line 839.Line 839 ("Then the entry that bears the highest duration...") is indented at the Windows tab level, suggesting it applies only to Windows. However, this statement is a common follow-up step for both OS variants and should be placed outside both tabs to avoid confusion.
🔎 Suggested fix for placement
Move line 839 outside the tab structure, between the Windows closing fence (line 838) and the next section header:
Get-Content correlation.log | ForEach-Object { ($_ -split '\|')[3] } | Sort-Object {[double]$_} ``` - Then the entry that bears the highest duration can be found by searching the file for this time. - === "Linux/macOS" +Then the entry that bears the highest duration can be found by searching the file for this time. + += "Linux/macOS" ```bash cat correlation.log | grep "<highest_time>" ```Alternatively, if the intent is to keep explanatory text within tabs, add the note to both the Linux and Windows tabs.
827-828: Consider refining phrase for clarity and conciseness.Line 828 uses "high time consumption," which is slightly informal. Consider using more direct terminology like "high latency" (to match the same sentence) or "long duration" for better consistency and clarity.
🔎 Suggested refinement
- If a method with a high time consumption cannot be identified, but still a high latency is observed, the following command can be executed to find the highest time recorded. + If a method with high latency cannot be identified, but latency is still observed, the following command can be executed to find the highest duration value recorded.

685-693: LGTM.The log isolation commands are functionally equivalent and correct.
801-809: LGTM.The Windows command correctly extracts the 4th field (duration) and performs numeric sorting via PowerShell's
Sort-Objectwith double cast, matching the Linux/macOS behavior.
813-825: LGTM.Windows commands for HTTP, JDBC, and LDAP analysis correctly extract the 4th field and sort numerically, matching the Linux/macOS equivalents.
